Today’s major browsers have a built-in tab hibernation function in order to improve resource usage. The purpose is to put inactive tabs into hibernation, thereby saving memory and releasing computer resources. This feature is very useful for users who open dozens or even hundreds of tabs at a time.

So what is the specific effect of this function, and how much computing resources are released for users? Now Microsoft has released their latest statistics.

Microsoft has added tab hibernation to the browser since Edge 105. When the memory usage of the device is close to the limit, it will automatically hibernate inactive tabs with high resource usage. According to Microsoft’s latest statistics (September data), in this month alone, the Edge browser managed to put 1.38 billion inactive tabs into hibernation to reduce the pressure on the memory of Windows devices. Hibernating tabs in this way saves an average of 83% of memory, Microsoft says.

In June of this year, Microsoft Edge officially released statistics (as shown below).

Over the past 28 days, we hibernated 6 billion tabs on Windows devices, saving 273.7PB of memory, or an average of 39.1MB per tab.

Judging from the total statistics of 6 billion tab pages in June, the average saving of 39.1MB per tab page is still of great reference value. Therefore, taking the data volume of the latest 1.38 billion dormant tab pages in September into the calculation formula, we can conclude that the memory saved by the Microsoft Edge browser in that month is about 54PB.

Considering that the current market share of the Edge browser is less than 4.5%, while Chrome’s market share has reached 65.8%, there is a 15-fold gap between the two in terms of market share, although Google has not released data such as how much memory is saved, But we can also imagine how big that number would be.
